16 Machine Parameters
599 IB-1501279-H
Set the vibration frequency to suppress when machine vibration occurs.
(Enabled at 50 or more.)
When not using, set to "0".
Related parameters: SP034/bit7-5
---Setting range---
0 to 5000 (Hz)
Set the inductive voltage compensation gain. Normally, set to "100".
Lower the gain when the current FB peak exceeds the current command peak.
---Setting range---
0 to 200 (%)
Set this parameter when the protrusion (that occurs due to the non-sensitive band by friction, torsion, back-
lash, etc.) at quadrant change is too large.
This sets the compensation torque at quadrant change (when an axis feed direction is reversed) by Short-
time rated %.
Whether to enable the lost motion compensation and the method can be set with other parameters.
[Type 2 "When SP033/bit9,8=10"]
Set the compensation amount based on the motor short-time rated current.
The standard setting is double of the friction torque. The compensation amount will be 0 when "0" is set.
Related parameters: SP033/bit9-8, SP039, SP040, SP041, SP227/bit2
[To vary compensation amount depending on the direction]
When SP041 (LMC2) is "0", change SP048 (LMC1) value in both of +/- directions to compensate.
To vary the compensation amount depending on the command direction, set this with SP041 (LMC2).
(SP048: + direction, SP041: - direction, However, the directions may be opposite depending on other set-
tings.)
When "-1" is set, the compensation will not be performed in the command direction.
---Setting range---
-1 to 200 (Short-time rated %)
Note that when SP227/bit2 is "1", the range will be -1 to 20000 (Short-time rated 0.01%).
When a relative error in the synchronous control is too large, set this parameter to the axis that is delaying.
The standard setting is "0". The standard setting in the SHG control is "50".
Adjust relative errors in acceleration/deceleration by increasing the value by 50.
---Setting range---
0 to 999 (%)
Set the imbalance torque.
---Setting range---
-100 to 100 (Short-time rated %)
Set the control time constant in dual feed back.
When the function is valid, the standard setting is "100". When "0" is set, the value is 1 ms.
When the time constant is increased, the operation will get closer to the semi-closed control and the limit of
the position loop gain will be raised.
However, this cannot be used when the spindle slip occurs in machine configuration such as V-belt drive.
